Our brand new quick formula has streamlined the lifting process so Diablo Lash Lift can be performed in under 15 minutes! This makes lifting your lashes at home easier than ever.

Not at all! Diablo Lash Lift is a maintenance-free solution. Forget the hassle of your eyelash extensions and live in a world where you can lift your lashes, then forget about them for a month or two!

Once complete, you will have beautifully long and lifted natural eyelashes for around two months! This depends entirely on your eyelash lifespan which can be anywhere between 5 and 10 weeks.

For a tighter/more dramatic lift, use the smaller lift pads. For a softer/more natural lift, use the bigger lift pads. 

Diablo Lift Pad Sizes

If you don't know which pad to choose, we recommend starting with the M pads.

If you find the pads are becoming unstuck because they are too long,  you can cut the ends of the pads so they fit your eyelid.

Yes! If you'd like to add tint into your lifting process, we recommend doing so after removing the fix lotion from your eyelashes.

Place a small amount of each product on either the inside of your elbow, the inside of your wrist, or behind your ear. Leave for 10 minutes, then wipe off. Wait 24 hours, if skin irritation occurs, do not use the kit.

Yes! If it's oil-free, Eyelash serum is a great idea as it will help to strengthen and lengthen your eyelashes ready for your next Diablo Lash Lift.

Yes! We think mascara can be a great combo with lifted lashes for special occasions. However, we're sure you'll completely stop using mascara every day after being wowed by your eyelashes with a Diablo Lash Lift!
Unfortunately, If you wear waterproof mascara or eyeliner, it is difficult to remove, and you can only use oil-based make-up remover which may weaken your lift. You can still use regular mascara or eyeliner, but we're sure you'll stop using mascara anyway after seeing your eyelashes with a Diablo Lash Lift!
Yes! Diablo Lash lift is completely water and eye-rubbing friendly. However, for the first 24 hours we recommend keeping water to a minimum to allow your eyelashes to set in their new lifted position!

If your lift didn't go to plan or you'd like a slightly different curl. Please wait at least 4 weeks before performing the lifting process again to avoid over-processing your eyelashes.
We don't recommend lash lifting while pregnant. Although it is considered safe, pregnant women experience a change in hormones which may have an effect on the results of the lash lift. 

Diablo Eyelash Serum contains a unique blend of peptides, vitamins and growth extracts that allow your eyelashes to reach their full potential.

Peptides stimulate new hair growth while the vitamins and growth extracts reduce lash loss, extend eyelash lifespan and ultimately allow your eyelash hairs to grow longer.

Diablo Eyelash Serum should be applied once every evening before bed. Simply apply one thin line across your eyelid like eyeliner and leave on overnight for best results.

You'll start to see growth in as little as 2 weeks. And you'll have visibly longer & thicker lashes after 8 weeks of using Diablo Eyelash Serum each night.

There are no side effects from using Diablo Eyelash serum and it is free from Allergens, Parabens, Hormones (Prostaglandin), Sulphates, Silicones and Fragrances.

The 3ml bottle will last approximately 3 months if applied once nightly.

Yes! However please clean your eyelids and remove your contact lens' before application each night.

No. Diablo Eyelash Serum will not change your eye color, since it does not contain Prostaglandin. 

Prostaglandin is a common ingredient found in eyelash serums and although it's great for eyelash growth, it can in fact change your eye colour and may also cause the darkening of your eyelid.

Yes! However, we'd highly recommend patch testing first. Just apply a small amount of the serum to either the inside of your elbow, inside of your wrist, or behind your ear. Leave for 24 hours to see if you have any sensitivity.
